PURPOSE:To prevent a dew formation on the surface of a ceiling material, arrange a suction port near an air blowing port, reduce an amount of air blowing for air conditioning and further eliminate any uncomfortable feeling caused by an air flow by a method wherein some guiding plates are disposed in front of air blowing ports and the conditioned air is blown along a front surface of the ceiling material facing to a room. CONSTITUTION:Air blowing ports 6 have a flat-plate guiding plate 8 so as to cover in a spaced-apart relation an opening of a ceiling material 1 connected to an extreme end of a duct 4. It has such a shape as one in which a blowing of conditioned air from an air blowing duct 4 is performed along a surface of the ceiling material 1 facing to the room, so that the surface of the ceiling material 1 facing to the room and acting as a radiation surface is directly adjusted in its temperature. During a cooling operation, a temperature at the surface of the ceiling material 1 is kept at a higher temperature than a dew formation point of the cooling air of the conditioned air, thereby the dew formation at the surface of the ceiling material 1 is prevented. In addition, a suction port 7 is disposed near the air blowing ports 6, thereby the conditioned air blown from the air blowing ports 6 is partly flowed into the room and it is possible to eliminate any uncomfortable feeling caused by an air flow speed. |
